DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

A riser (10) for a snow blowing attachment (11) comprising a snow blowing attachment frame (13) including a wheel axle (15) and two spaced attachment arms (26) extending perpendicularly therefrom. A pair of wheels (14) rotationally connected to the wheel axle (15) and adapted to support the snow blowing attachment frame (13) above a driving surface (17). A pair of connecting members (12) each pivotally connected to the spaced attachment arms (26) and adapted to be removably connected to two lower points of a three point hitch (18′) of a tractor (20).

A wishbone frame (22) has two spaced distal ends respectively pivotally connected to the spaced attachment arms (26) and a proximal end positioned a distance from the wheel axle (15). A stem member (24) is attached at one end to the proximal end of the wishbone frame (22) and extending in substantially the same direction as the two spaced attachment arms (26). A hydraulic piston (16) is pivotally connected at one end to the proximal end of the wishbone frame (22) opposite from the stem member (24) and is adapted to be operatively and pivotally connected at an opposite end to an upper point of the three point hitch (18″). The hydraulic piston (16) and the pair of connecting members (12) form a three-point triangular hitch. In this manner, when the snow blowing attachment (11) is secured between the two spaced attachment arms (26) and the stem member (24), the hydraulic piston (16) is used to pivot the wishbone frame (22) with respect to the wheel axle (15) and thereby pivot the snow blowing attachment (11) with respect to the driving surface (17).

The stem member (24) has a plurality of attachment holes (25) therein along its length adapted for adjustably connecting to a top portion of a snow blowing attachment.

As to a further discussion of the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided.

With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.
